Grape hard branch cutting method

Abstract

The invention relates to the technical field of cuttage, in particular to a grape hard branch cutting method. The method comprises the following steps that in the first ten days of April, cutting slips are cut, the length of the cut slips ranges from 10 cm to 15 cm, 1-2 buds are reserved, the distance between an upper cutting opening and the buds ranges from 0.8 cm to 1.2 cm, and stumping cuttingis conducted; a lower cutting opening is 0.5-1 cm close to the lower portion of a joint and cut into a horse ear shape, and a cutting is obtained; a base part of the cutting is subjected to rooting treatment; the cutting is placed in fine sand on a hotbed for rooting accelerating; and cuttage is carried out on the cutting subjected to rooting accelerating. Hard branch cutting is mainly utilized, operation is easy, the propagation coefficient is high, the cost is low, the excellent characteristics of an original variety can be kept, the cutting efficiency and survival rate can be better improved, and the cost is saved.

Description

technical field [0001] The invention relates to the field of cuttage technology, in particular to a hard branch cuttage method for grapes. Background technique [0002] Grape seedling raising technology is one of the key links for high-yield and high-quality cultivation of grapes, which directly affects the growth rate, growth and yield per unit area of ​​the tree. The widely used grafting methods mainly include green branch grafting and hard branch grafting. Green branch grafting refers to the use of semi-lignified scions to graft onto resistant varieties or rootstocks during the growing season. Cut off above the scion bud, cut off the scion under the bud, and then cut the scion from a place close to the bud base. Find a good angle and make a successful cut. Cut one knife on each side of the scion to form a wedge shape. Then from the center of the cross section of the rootstock, a knife is cut vertically to cut a long split of about 3.0 cm. Immediately insert the cut scio...

Problems solved by technology

[0004] The existing technology mainly includes green branch grafting and hard branch grafting. The survival rate of green branch grafting is relatively high, but the breeding cycle is long, the grafting interface is not firm, and it is easy to break. The process of hard branch grafting is very complicated, and the purity of the variety cannot be guaranteed. Higher, there are often technical problems such as poor joint healing, poor quality of root stock, unsuitable environmental conditions, confusion of varieties, unreasonable transplanting process, etc., resulting in poor survival rate of grafted seedlings, and death when not transplanted or after transplanting The phenomenon

[0005] At present, the grape seedling market in my country is complex and mixed. The purity of various grafted seedlings is insufficient and the price is high. The current grafting method is relatively complicated and requires professional grafting technology and machine use technology. The mechanical and labor costs of the whole process are relatively high. And there is the problem of low survival rate. After grafting, the genetic traits of the mother plant and the excellent characteristics of the original variety are often not fully retained. The amount of seedlings raised is usually small. For individual farmers, the grafting technology is often difficult, which is not conducive to expanding the cultivation area of ​​grapes. and the user population
